LESSON PLAN
Learning Area: MATHEMATICS 6
Third Quarter
Time Duration: 50 minutes
Learning Competency: Reads and interprets electric and water meter Code: M6ME-IVd-100
Key Concepts / Understandings to be Developed:
To read electric meters:
1. Always read all the dials from right to left, starting from Dial E to Dial A.
2. Read the number of the pointer of the dial. When the pointer is between two
numbers, the lower number is recorded
3. If the pointer appears to be exactly on a number, check the dial to the right to find out
the correct reading
• If the dial on the right has passed zero, then use the number the pointer is pointing on
the dial you are reading
• If the dial has passed zero, then make use of the smaller number, then make use of thee
smaller number of the dial you are reading
To read water meters:
1. Start reading from right tp left (clockwise). Read the number by the pointer of the
dial. When the pointer is between two numbers, the lower number is recorded.
2. When the pointer is directly on the number, look at the dial to the right. If it passed
zero, use the next higher number. If the dial has not passed zero, use the lower
number. Record the numbers from right to left.
I.
Objectives:
Knowledge: Read and interpret electric and water meter reading
Skills:
Records the reading shown by the dials of electric meter and water meter
Attitudes:
The wise use of electricity and water
Values:
Conservation of electricity and water consumption
II. Content:
Reading and interpreting electric and water meter reading
III. Learning Resources/ Materials:
Lesson Guide in Elementary Mathematics Grade 6 pp 406-411
Model of electric meter, and drawing of water meter
Projector for power point presentation
IV. Procedure:
A. Preparation
1. Drill
Mental computation:
What is added to 5 to get 9?
What happens to 9 when you add 1?
2. Review
Review on place value and the relation on each digit to another digit in a
given number.
Use flash cards-Review on Subtraction
3. Motivation
Ask the pupils
a. the electrical appliances they have at home. Elicit from them which of
these appliances consume the most electricity.
b. how much they pay for their monthly electric bill. Get some reactions.
4. Presentation
Let them watch a short clip about water and electricity consumption.
Then show the whole class a model of an electric meter and actual water
meter (improvised instructional material). Illustrates how the dials move for
electric meter and for water meter. Then the pupils are asked to read the
electric and water consumption as shown by the dials. This is done several
times.
Comparison is made between consumptions.
B. Lesson Proper
1. Activity (Differentiated Activity)
Group the pupils into four groups. Groups 1 and 3 for station I and Groups 2
and 3 for station 2. Groups 1 and 2 will present their work in a form of role
playing and groups 3 and 4 as a reporting. A rubric will be use to assess
group performance.
For Station 1 – study the table and compute the kwh used.

Consumption
2. Analysis
Ask the class follow-up questions:
In Station 1:
Which household consume the most? The least?
Which two houses consumed almost the same kwh? What can you say about
their bill?
As a member of the household, how can you lower your electric bill? Why is it
important to use electricity wisely?
In Station 2;
In what month consume the most water? Least water?
What is the average monthly consumption?
How many liters of water did they use? What is the equivalent in cubic meter?
3. Abstraction
How the dials of electric meter move? How do you read the dial of a meter?
How do you read the water meter? How do you solve for the monthly
consumption?
Give reminder that water consumption uses cubic meter while electricity uses
kilowatt as its unit of measurement.
Make them see that the previous reading is smaller than the present reading.
4. Application
A. Draw a dial to show the readings and get the difference.
1. 4 218
2. 4 732
B. Marjorie’s records of her family’s water consumption reads this way:
Initial reading
December
0031.495
January
0042.180
February
0053.921
Answer the questions: What was the average monthly consumption of
Marjorie’s family?
C. Generalization
To generalized the lesson, ask a student on how to read electric meter and
another student for water meter.
To electric meters:
1. Always read all the dials from right to left, starting from Dial E to Dial A.
2. Read the number of the pointer of the dial. When the pointer is between
two numbers, the lower number is recorded
3. If the pointer appears to be exactly on a number, check the dial to the
right to find out the correct reading
• If the dial on the right has passed zero, then use the number the pointer is
pointing on the dial you are reading
• If the dial has passed zero, then make use of the smaller number, then
make use of three smaller number of the dial you are reading
To read water meters:
1. Start reading from right to left (clockwise). Read the number by the
pointer of the dial. When the pointer is between two numbers, the lower
number is recorded.
2. When the pointer is directly on the number, look at the dial to the right. If it
passed zero, use the next higher number. If the dial has not passed
zero, use the lower number.
Record the numbers from right to left.
(the teacher show example of electric meter and water meter)
D. Values Integration/ Subject Integration
Do you think water is important? How about electricity? Explain your answers.
Can you save water? How? Why is it necessary for us to save water?
V. Evaluation:
A. Give the meter reading, then give the electric consumption with the correct unit of
measurement.
Meter A
Meter B
B. Answer the problem.
Allanic family’s water reading was 0457816 for the month of October and
0457952 for the month of November. How many cubic meters of water did the family
consumed?
VI. Assignment:
(To be answered by students who got below the passing score.)
Compute the electric consumption from present to previous in your household.
Explain how you can help in saving for electricity expenses.
Enrichment Activity: (varied answers, use rubric in checking)
Why is it important to learn how to read water and electricity meter and how in
your own way can you help in saving electricity and water expenses of your family?

Group Evaluation: You are going to evaluate your group members as part of the group oral presentation
rubric. Ask yourself the following question when you are evaluating your peers, “Did__________(name)
fulfill his or her responsibilities within the group?” You are then to give that person a score from 1 to 4, 4
being the highest based on your response to the question. Final scores will be under my consideration
based on the score and the reason behind each.
